Panchang in Sevan, Gegharkunik, Armenia Thu 20 May 2100

Smartas test Ekadashi at sunrise: it holds sunrise on Thu 20 May only, at 05:39: Thu 20 May. Vaishnavas test arunodaya: Dashami ended at 14:09 Wed, before it (04:03–05:39).

Mohini Ekadashi: every date in Sevan

The Moon gains on the Sun about 12° a day. Each 12° of lead is one tithi: 120°–132° is the 11th, Shukla Ekadashi. A day takes the tithi in force at its sunrise, 05:39 here. Dashami ended at 14:09 Wed, before it. Ekadashi ends at 11:22, when the lead reaches 132°. The lead passed 0° at the new moon of 9 May, so the Moon is waxing: Shukla paksha.

The night of Wed 19 May ran from sunset 20:13 Wed to sunrise 05:39, 9 h 26 m. Cut into 15 muhurtas of 37 m, its 14th is Brahma Muhurta, the one before the last.

Daylight here, 05:39 to 20:14, splits into 8 choghadiyas of 1 h 49 m. Their names follow a fixed order that starts from the weekday, and each name is counted good, neutral or bad.

The night here, 20:14 to 05:38 Fri, splits into 8 choghadiyas of 1 h 10 m. Their names follow a fixed order that starts from the weekday, and each name is counted good, neutral or bad.

The fixed stars divide the Moon's path into 27 nakshatras of 13°20′, each in 4 padas of 3°20′. Hasta spans 160°00′–173°20′; the Moon entered its pada 1 at 160°. It leaves at 23:02, for Chitra.

Add the Sun's and the Moon's places among the stars: 33.9° + 162.7° = 196.6°. The sum, cut into 27 parts of 13°20′, gives the yoga: 186°40′–200°00′ is the 15th, Vajra. It ends at 10:53, then Siddhi.

A karana is half a tithi: 6° of the Moon's lead, so the first half of Ekadashi is Vanija and the second Vishti. Vanija ended at 00:49, when the lead reached 126°; Vishti runs until 11:22.

A Hindu day runs from one sunrise to the next, not midnight to midnight. This one runs 05:39 to 05:38 Fri, so the hours after midnight still belong to Guruwara.

An amanta month runs from new moon to new moon and takes its name from the rashi the Sun is in at the new moon that begins it: Mesha gives Vaishakha. The Sun enters Vrishabha on 16 May, inside the month. The next new moon, 8 Jun, finds it in Vrishabha and begins Jyeshtha.

A purnimanta month runs from full moon to full moon, so its waning half comes first. It shares its name with the amanta month that its second half falls in: the new moon of 9 May, with the Sun in Mesha, began Vaishakha. This Shukla paksha reads Vaishakha in both counts.

A samvat year begins with Chaitra, the month whose new moon finds the Sun in Meena: 9 Apr 2100, 20:18 Fri. Since then the Sun has moved 39.3° round the stars. Vikram Samvat numbers that year 2157; Shaka Samvat numbers it 2022.
